A person with knowledge of the deal says the Dallas Cowboys have agreed on a one-year contract with quarterback Mark Sanchez, who will back up rookie Dak Prescott while Tony Romo recovers from a back injury.
Sanchez was released by the Denver Broncos on Saturday, clearing the way for the six-year veteran to sign with another team. The person confirmed the agreement to The Associated Press on condition of anonymity because the contract can't be signed until Sunday.
The Cowboys placed running back Darren McFadden on the non-football injury list, sidelining their leading rusher from last season for at least the first six games. He broke his right elbow during the offseason.
Dallas has to decide whether to place Romo on the injured reserve-return list after he broke a bone in his back in a preseason game at Seattle. Romo would miss the first seven games if he's on that list.
